Use Navigate herbicide for control of certain aquatic weeds in: ponds; lakes; reservoirs; and marshes. This product is designed to selectively control the weeds listed on the label. While certain other weeds may be suppressed, control may be incomplete. Reduced control may occur in lakes or ponds where water replacement comes from bottom springs. Sculpin G is formulated on biodegradable granules that, when applied to water bodies, immediately delivers the herbicide down to the critical areas for controlling target weeds. There are no restrictions on the use of treated water for recreational purposes, including swimming, fishing and domestic purposes. There are no restrictions on consumption of treated water for potable use by livestock, pets, or other animals.
